CURRENT-MOTOR.

Specification of Letters Patent.

I a'tented Aug. 6, 1912.

Application filed Derringer '28, 1911. Serial No. 668,259.

To all whom it may concern.

Be it known that I, T HOMAS H. VALKER,

, a citizen of, the United States, residing at Mullan, in the county of Shoshone and State of Idaho, have invented certain new and useful Improvements in Current-Motors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make'and use the same.

This invention relates to improvements in current motors.

The object of the invention is to provide a current motor which will be simple, strong, durable and inexpensive in construction, efficient and reliable in operation and which is particularly adapted for elevating water for irrigating purposes.

Vith this and other objects in view the invention consists of certain novel features of construction, and the combination and ar' rangement of parts as will be more fully described and claimed.

In the accompanying drawings :-F igure 1 is a side view of my Improved current.

motor; Fig. 2 is a top plan View; Fig. 3 is an end view thereof Fig. 4 is a vertical cross section on the line 44 of Fig. 1 Fig. 5 is a detail perspective view of the brake mechanism of the motor; Fig. 6 is an enlargeddetail view of one of the hubs for the spokes forming the ends of the cable supporting drums.

My improved current motor comprises a suitable frame 1 provided with standards 2 which are set into the bed of the stream in which the motor is to be arranged. In the frame 1 at suitable distances apart are arranged bearings 3 and 4. In the bearings 3 and 4 are revolubly mounted cable supporting-drums 5 and 6 each of which comprises a shaft 7 having fixedly mounted thereon at suitable distances apart, hubs 8. The hubs 8 have formed thereon a series of radially projecting spoke attaching arms 9 to which are bolted the inner ends of a series of radially projecting spokes 10 the outer ends of which are secured to annular rims 11. The spokes 10 and rims 11 form the ends or heads of the cable supporting drums 5 and 6 and said ends or heads are connected together by annular plates of suitable width having therein a plurality of water discharging passages or as shown 8 in the drawings, said heads may be connected together by a series of segmental plates 12 spaced apart to form a plurality of water discharging passages through which the water may freely flow as the drums are rotated in the stream.

Arranged around and secured to the mental plates forming the annular surface of the drums are two or. more annular cable receiving channel shaped rings or bands 13 which provide grooves or channels to re ceive the blade supporting and drum operating cables letwvhich are engaged therewith and have secured thereto at suitable intervals a series of drum operating blades or paddles 15. The paddles 15 are in the form of plates or boards of suitable width and having a length corresponding approximately with the length of the drums, said plates or boards being secured to the bars 1 or cleats 16 the inner ends of which are connected by eyes or loops 17 with the cables 14. The outer ends of the cleats are connected by short chains or cables 18 to the outer operating cables 14 whereby the blades or paddles are held in an operative position v against the pressure o f the current, said pressure of the current thus being applied to the cables 14 to turn the drums.

On the supporting frame 1 at suitableS positions are arranged platforms 19 upon which an operator may stand when adjusting or repairing any of the parts of the motor and for regulating the braking mechanism by which the speed of the motor 90 is cont-rolled. Thebraking mechanism is arranged to be engaged with the drum 6 and comprises a brake bar or beam 20 which is supported by posts or standards 21 the lower ends of 'f'hich are loosely engaged with one of the platforms 19. Secured to the brake bar or beam 20 are'brake shoes 22 having segmental outer surfaces adapted to be brought into engagement with the annular surface or side of the drum 6 with 109 greater or less pressure thereby retarding the movement of said drum and through the same the movement of the cables 14 and the drum 5, to a greater or less extent as may be desired. The brake bar or beam 20 is 105 adjusted to bring the brake shoes into greater or less forcible engagement with the outer surface of the drum by means of brake adjusting rods 23, the innerends of which are loosely connected with the shaft 119 of the 'itiigedly mounted sprhcltct which are arranged hearin in which is rev-- 5 k 'into the tank from which the Water will I provided Wit" crating hand turned on the it i and thus draw the. engagement in the drum are readily brake bar into operaiar side of.

On the Topper ends of the piies *2 arranged a tank supporting frame 31 o which is arranged a Y J T bottonr-of which the app re pipes 29 are connected.

Withand driven by sprocket gears 39 fixed on a conveyor operating shaft .0 journaled in suitable beari gs in the lower portion of the tower and 3h which is. a so fixed a sprocket gear di with which the drive chain 2? from the sprocket gear 21 is connected. By thus connecting the motor with the Water eievating mechanism herein d rihed it will be seen that the Water of the stream Will be elevated by the ohibly mounted the upper endless water eievator.

Kits 33 of he conveyor and discharged ose-attic V will thus be seen that iny' ntcproved motor is particularly adapted for operat ing a Water elevating apparatns'for producing a supply of Water for irrigating purposes,

My improved motor requires little or no attention, is economical in use as there is practically no A e ope arter the same has been .in- :l the motor is composed of coin rev; parts which are not liable to er 01 to require adjustment. ioregoing description takenv in with the accompanying draw- .7 mstruction and operation ot the will be readily understood Wiihout a more extended explanation.

thus described my invention, what ,urrentmotor comprising a supporting cabie, supporting drums revolubl'y mounted. in said frame, said drums comprising heads each of which consists of a. hub having radially extending arins, a series pokes secured at their inner elids to aid :lar bands connecting ti symkes and segment-1H i, t said bands to form the suiface'of the drums, annu shaped cable receiving rings "aecu id? to said annuiar surface of the drums, operating cab es engaged with said channel shaped rings whereby the drums are operatively onnected together and driven, a series of blades having a loose connection with said cables, a braking mechanism adapted to be engagedwith one of said dru'ms whereby the speed of the motor is retarded, and a power transmitting gear fixed to the 'co acting drum whereby the power of the'motor, may be transferred.

In testimony whereof I have hereunto set. my hand in presence of two subscribing Witnesses.
